Does anyone use these?

I have 2 leopard geckos and 2 fire bellied toads. I started a dubia roach colony hoping to feed everyone from. The geckos love the dubias, the toads do not. Even if they catch them, they just spit them out. Same with my sisters tree frogs (green tree frogs), they don't spit them out, they just don't eat them. So we've been stuck buying crickets, which I hate. I came across a good deal on Lateralis ($10 for 1000, $10 for shipping), but they were out of everything but new hatch. I bought 1000, and have been raising them. They're not yet big enough to feed exclusively, but the frog and toad reactions have been favorable. They like them. They move around more than dubias and don't hide or burrow. They're much more cricket-like.
